The International Equestrian Federation (FEI) have voted overwhelmingly to change their statutes to allow Princess Haya Al Hussein of Jordan to run for a third term as president.

A total of 103 national federations voted in favour of the amendment with just three against during a general assembly of the FEI in Lausanne on Tuesday.

Princess Haya, daughter of the late King Hussein of Jordan, had herself been behind the introduction of two four-year terms as the limit on the FEI president's term in office in 2006.

Her husband is Sheikh Mohammed bin Rashid Al Maktoum, the ruler of Dubai and Prime Minister of the United Arab Emirates - one of the dominant personalities on the thoroughbred racing circuit.

The Sheikh owns the Goldophin stables in England whose reputation has been severely tarnished by a doping scandal.

The doping of 22 horses - including the surprising 2012 St Leger winner Encke - resulted in an eight year ban for the man held responsible, trainer Mahmood Al Zarooni.
